Research Crossroads

[dicapino]

I am a new MS student at a school in Texas. I am at a crossroad on choosing a research topic, First, I need to show my interest in the thesis option before Spring 2017. To be more specific its an MS MECH Engineering program. I have deep passion for thermo-fluids research, but since coming to the US I want to do something like Design, Manufacturing or Control.

I am not bent on getting a Phd after my MS but I want to do research work; at least to for accomplishment and  yeah a lower tuition.

My questions

1)Get into an area I am familiar with or just get into something not theorectical like thermofluids.

I am very confused.
